While it may start off small, the coordinate panty to Bra-llelujah yields big results! Featuring comfortable, contouring hosiery yarn and banded double-layer compression, Undie-tectable® is a total tummy tamer. These bottoms seamlessly transition to skin because visible panty lines are never in style!

Rated 1 out of 5 by Shelleybaby Undie-tectable is not the right name
This panty fit horribly! I purchased a generous size for my actual size and pulled this panty out of you know where all day long! I returned this panty and do not plan to make any other purchases from Spanx as the boy shorts were just as bad. My search continues for well fitting panties that do not show lines and control small issues.

Rated 1 out of 5 by Jenny071071 Regret this purchase
The quality of the item is good, it feels true to the size, however the back part is very low cat, so the material keeps getting inside, so you constantly have to pull it out. Tummy control is good, but it rolls down, so you have to pull it up. I regret this purchase.

Rated 1 out of 5 by fluffylady not for somone with a big tummy
For me these panties are detectable. The back has too much fabric. Excess hanging below my butt. The front fabric is too short. The leg openings cut too high in the front. If the waist is placed where it is supposed to be then the belly hangs out below the leg openings. If you place the waist lower in the front to cover the belly then it rolls down. So if you have a flat butt and big tummy it will not work. A very expensive purchase faux paus to make. Assuming underwear still is unreturnable.

Rated 1 out of 5 by Kim007 Nothing seems right
The panty fits but top part rolls down and doesn't stay up. The legs doesn't stay, both legs ride up. If I had wanted a thong, I would have bought that one!

Rated 5 out of 5 by Jewelia I love them & wear 3 pairs layered everyday
I don't know what I did without these, I live in them...a lot of them!!!! I have a lot of joint pain & started wearing these to support my hips & SI joint & the fabric is wonderful... So comfortable & doesn't get too hot. They do create a fat roll above them which causes the edge to roll down, so I wear 3 pairs at a time & layer them from the bottom fold down seam, so each pair covers a bulge... The 1st pair, I pull all the way up & anchor under my bra to prevent bulges from the others, the 2nd goes just below the folded seam to support the mid-back, the 3rd I wear one size smaller than the others, in a normal panty position, to suck in my dreaded fat roll & support my joints like a SI belt. I many times will add a thin-stincts tank over the top to hold it all in place, but isn't necessary. My only complaint is that the stitching holding the folded band always rips out pretty fast which gets very pretty expensive, considering I wear 3 everyday... But I seriously couldn't live without them!!!!

Rated 1 out of 5 by Lizzytish This product rides up
This is my first spanx product and I am disappointed.
After putting it on it felt good but the back rode up quickly and after a few hours the whole front part rode up making it almost like a thong in back and front. Yes unusual - it is my size and I imagine to eliminate all the ride up I should be ordering the longer leg. I live in FL where it is warm so I didn't want to do that.
I did review the size chart and ordered my appropriate size. It is hard to tell whether this product is either small or large for me.

Rated 3 out of 5 by Jof1972 Great panty as long as your tummy isn't too big!
I bought two pairs of these panties as I'm quite small in the butt area but my problem area is the tummy and while the fabric is really lovely and comfortable and they do do exactly as they say, I found that if I sit the pants where they should be which is just on or above the belly button they actually roll down as soon as you sit down which is not ideal. I had to pull them right up to the waist line so they wouldn't roll down which was OK, they had the stretch to do that but I was hoping to just be able to wear them a little lower. I won't be able to wear these with jeans as they either show above the jean or roll down below my belly. Not the best look. Probably great if you don't have much of a belly and just want a little smoothing though.

I have a 30 inch waist and my hips are about 43 inches!!!!!!!!!!!!!!! I got this way by taking predisone. Wearing the Undie-Tectable Panty feels like a second skin. It goes on very easy and is so comfortable. I see no lines under my shorts or pants. I'm definitely buying more!
